A link to a set of decoupled N=2 supersymmetric harmonic oscillators with alternating sign in the Hamiltonian is introduced. Symmetries of the model are discussed in detail. The investigation of a quantum counterpart of the constructed model shows that the corresponding Fock space contains negative norm states and the energy spectrum of the system is unbounded from below.","authors_text":"Ivan Masterov","cross_cats":["math-ph","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2015-03-12T12:51:30Z","title":"N=2 supersymmetric Pais-Uhlenbeck oscillator"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1503.03699","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:f41f0cf3dfd1b8da7ba08586a0aa43e60ac4497ecfc174687cc147dcb68f9ebf","target":"record","created_at":"2026-05-18T02:00:02Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"4643468c35e3dd2b78bff1a6a352db75ac2ef682782f1ef076cb07e4021a6d0b","cross_cats_sorted":["math-ph","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2015-03-12T12:51:30Z","title_canon_sha256":"61ec4df0808e25345dcd261300845d27c333b856b12f0ec74052de3af4ffa900"},"schema_version":"1.0","source":{"id":"1503.03699","kind":"arxiv","version":2}},"canonical_sha256":"caaa1740a095ecb4ae9c1b72fd154d4d7eeff05993ac3924f98eb75793f180dd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"caaa1740a095ecb4ae9c1b72fd154d4d7eeff05993ac3924f98eb75793f180dd","first_computed_at":"2026-05-18T02:00:02.105677Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:00:02.105677Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"45ujsU3ZxaY4/8UQtjc3jQQaqdZNU7x89nomfW9raV65PANdRKFopje5afyfRp0R9FcUvXu3/BW2vdX+YZKfBA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:00:02.106216Z","signed_message":"canonical_sha256_bytes"},"source_id":"1503.03699","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f41f0cf3dfd1b8da7ba08586a0aa43e60ac4497ecfc174687cc147dcb68f9ebf","sha256:bcdea9ab1f107aeaab34ec6cb9ee4aa056b5f2b1808e086780ee11c578458cc0"],"state_sha256":"167e77355bbd8e71c808992a3f16da2ec7e03e9d4f20bdee58a80cc4c5d004f2"}
